UIView在iOS中为二维反弹球（挤压和拉伸）设置动画

正在寻找动画，如使用挤压和拉伸反弹球，在可可使用核心动画

1-反弹球动画

;;;;

以下代码将生成上面的动画：

CAKeyframeAnimation *trans = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.y"];
NSArray *values = @[@(-200),@(20),@(0)];
trans.values = values;
NSArray *times = @[@(0.0),@(0.85),@(1)];
trans.keyTimes = times;
trans.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
trans.autoreverses = YES;
trans.duration = 1.0;
trans.repeatCount = INFINITY;

CAKeyframeAnimation *scaleXAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform.scale.x"];
NSArray *scaleXValues = @[@(0.75),@(0.75),@(1)];
scaleXAnimation.values = scaleXValues;
NSArray *scaleXtimes = @[@(0.0),@(0.85),@(1)];
scaleXAnimation.keyTimes = scaleXtimes;
scaleXAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
scaleXAnimation.autoreverses = YES;
scaleXAnimation.duration = 1.0;
scaleXAnimation.repeatCount = INFINITY;

CAKeyframeAnimation *scaleYAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform.scale.y"];
NSArray *scaleYValues = @[@(0.75),@(1),@(0.85)];
scaleYAnimation.values = scaleYValues;
NSArray *scaleYtimes = @[@(0.1),@(0.5),@(1)];
scaleYAnimation.keyTimes = scaleYtimes;
scaleYAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
scaleYAnimation.autoreverses = YES;
scaleYAnimation.duration = 1.0;
scaleYAnimation.repeatCount = INFINITY;

[_ballView.layer addAnimation:scaleXAnimation forKey:@"scaleX"];
[_ballView.layer addAnimation:scaleYAnimation forKey:@"scaleY"];
[_ballView.layer addAnimation:trans forKey:@"trans"];

CAKeyframeAnimation *trans = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.y"];
NSArray *values = @[@(-200),@(20),@(0)];
trans.values = values;

[_ballView.layer addAnimation:scaleXAnimation forKey:@"scaleX"];
[_ballView.layer addAnimation:scaleYAnimation forKey:@"scaleY"];
[_ballView.layer addAnimation:trans forKey:@"trans"];

你试过什么了吗？您是否能够真实地上下移动视图？那个动画会重复吗？您是否能够沿一个轴缩放视图？你能把这些时间安排在一起吗？等等。你是想创造同样的假3D效果，还是那只是一个弹跳球的插图？@DavidRönnqvist我添加了一些代码，这就是我想你在寻找的CAKeyframeAnimation@DavidR是的，我在找你的梦想你试过什么了吗？您是否能够真实地上下移动视图？那个动画会重复吗？您是否能够沿一个轴缩放视图？你能把这些时间安排在一起吗？等等。你是想创造同样的假3D效果，还是那只是一个弹跳球的插图？@DavidRönnqvist我添加了一些代码，这就是我想你在寻找的CAKeyframeAnimation@DavidRönnqvist是的，我正在寻找答案，我会在未来24小时内实施，如果它工作正常。我会接受你的答案。谢谢你，这真的帮了我。当然，祝你愉快，我得到了你的答案，我会在接下来的24小时内实施它，如果它工作正常的话。我会接受你的回答。谢谢你，这真的帮助了我。当然，享受和快乐的编码
